Title: Production of stamper for optical disk
Inventor: HIRATA ICHIRO
IPC: C25D1/00
Filed: 1988-07-29
Abstract: PURPOSE:To increase the efficiency of production of a stamper for optical disks and to prolong the service life by slowly increasing electric current from a low value, carrying out electrodeposition with constant high electric current, carrying out electrodeposition with low electric current, slowly increasing the electric current again and carrying out electrodeposition with constant high electric current. CONSTITUTION:When electrodeposition is carried out in one of stages for producing a stamper for optical disks, electric current is slowly increased from a low value close to zero at the beginning of electrodeposition to a relatively high value and electrodeposition is carried out with constant high electric current. Electrodeposition is then carried out with low electric current so as to obtain a prescribed hardness. The electric current is slowly increased again and electrodeposition is carried out with constant high electric current to form a film whose thickness corresponds to the thickness of a film removed in the subsequent polishing stage. The efficiency of production of a stamper for optical disks can be increased and the service life can be prolonged.
